Detailed ways

The existing potato chip processing method cannot avoid the contact between potatoes and air, so it is very easy to cause browning of potatoes during processing. In order to avoid browning of potatoes during processing, the present invention proposes a new potato chip. The potato chips are processed by cleaning the potatoes, peeling, slicing, aging, cooling, and microwave heating and drying in a closed environment, and then oiling. Fried and seasoned, this greatly reduces the chance of potato contact with oxygen during the entire potato chip processing process, which can effectively prevent the polyphenol oxidase (PPO) in the potato from contacting oxygen in the air, avoid oxidative polymerization, and can effectively Prevent potatoes from browning, thereby ensuring that the final potato chips produced are of higher quality.

Specifically, the potato chip processing method includes the following steps:

A. Wash the potatoes;

B. Peel the cleaned potatoes in a closed environment and rinse them with clean water;

C. Transfer the peeled potatoes to a closed environment for slicing;

D. Heat the cut potato slices in a closed environment until the potato slices are ripe;

E. Transfer the mature potato slices to a vacuum environment for cooling;

F. Microwave heating and drying the cooled potato slices in a closed environment;

G. Fry the dried potato slices;

H. Season the fried potato slices.

In the above embodiment, in order to completely avoid contact between potatoes and oxygen in the air, in step B, an inert protective gas is filled into the closed environment during the peeling process; in step C, during the slicing process, In the step D, an inert protective gas is filled into the sealed environment during the heating process; in the step F, the sealed environment is filled into the sealed environment during the microwave heating and drying process. Pour in inert protective gas. By introducing inert protective gas during the peeling, slicing, ripening and drying processes, the inert protective gas will not have any chemical reaction with the potatoes, so the potatoes can be effectively prevented from browning. Furthermore, the inert gas can be argon, helium and other inert gases. As a preferred way, the inert protective gas is nitrogen. Since nitrogen contains the largest proportion in the air, it is easy to obtain and the cost is low.
